Perineural Therapy segmentation by type revolves around injectates that modulate local neuro-inflammation. Dextrose-based formulations remain the anchor, typically 5% dextrose in water, because they are inexpensive, safe, and supported by level-II evidence for neuropathic pain. Platelet-rich plasma (PRP) variants command higher pricing, as autologous growth factors are concentrated to 3–7× baseline, extending analgesia beyond six months in refractory entrapment syndromes. Steroid-containing solutions are losing share (now <12% of global volumes) amid concerns over glycemic spikes and tendon weakening, yet persist for acute post-surgical neuralgia where rapid anti-inflammatory action is required. Emerging botulinum toxin and allogeneic exosome segments are <1% of 2023 revenues but growing at 18% CAGR as early trials show prolonged sodium-channel blockade. Overall, the type mix explains 42% of segment-level revenue variance, with dextrose and PRP together contributing 78% of 2023 global sales, illustrating how injectate choice directly scales procedure economics.
